The case for Giacomo Agostini
Fifteen world championships and 122 Grand Prix wins, neither total seriously threatened in fifty years. Agostini won eight 500cc titles, seven of them consecutively from 1966 to 1972, and seven 350cc crowns, frequently taking both on the same afternoon. His premier-class record reads 68 wins from around 120 starts, a strike rate above 55 percent that nobody in the modern era approaches, and he once won 20 consecutive premier races across 1968 and 1969, including a clean sweep of the 1968 season. The standard objection is machinery: MV Agusta's multi-cylinder fours were often the only genuinely competitive bikes on a thin grid. He answered it in 1975 by leaving MV for Yamaha and winning the 500cc title on a two-stroke at 33, the first two-stroke premier crown and the end of MV Agusta's seventeen-year run. He also won ten Isle of Man TTs before refusing to return after Gilberto Parlotti's death in 1972.
The case for Geoff Duke
Six world championships: the 500cc title in 1951, 1953, 1954 and 1955, and the 350cc title in 1951 and 1952. Duke won 33 Grands Prix and 50 podiums from 89 starts, 22 of the wins in the premier class, and was the first rider to take premier-class titles with two different manufacturers, Norton in 1951 and Gilera from 1953. He is also the sport's first genuine modernist: he commissioned a local tailor to make him a one-piece racing suit, replacing the two-piece leathers everyone else wore, and his smooth, low-drag style became the template for road racing technique. In 1956 the FIM suspended him for six months for supporting a riders' strike over start money, which cost him any chance of a fourth consecutive 500cc crown.
